Re: [PATCH 1/1] commit-graph: define GIT_TEST_COMMIT_GRAPH

I see these failures, too, but I believe they are due to
ds/commit-graph-with-grafts not being merged to 'next' yet. The
purpose of that branch is to fix these test breaks. The environment

A separate "ping" would have helped me.  Will merge it down to
'next'.
